[0025] Referring to Figure 2 and Figure 3 , it is further obtained that the adjustment mechanism 5 includes a first protective plate 7 and a second protective plate 8. A hinge 9 is installed between the first protective plate 7 and the sliding seat 3. The second protective plate 8 is movably sleeved on the outside of the first protective plate 7. A plurality of screw holes 10 are opened through the inner and outer sides of the first protective plate 7. A plurality of positioning holes 11 are opened through the inner and outer sides of the second protective plate 8. A positioning bolt 12 is connected and installed between the positioning hole 11 at the bottom end and one of the screw holes 10. A stud 13 is fixedly installed at the top of the outside of the first protective plate 7. A bolt cap 14 is connected to the periphery of the stud 13.

[0026] The sliding seat 3 is arranged to slide up and down on the outside of the guide rail 4. The first protective plate 7 is arranged to rotate movably on the top of the sliding seat 3.

[0027] The second protective plate 8 is sleeved outside the first protective plate 7 and is arranged to slide up and down. The distance between each screw hole 10 is equal to the distance between each positioning hole 11.

[0028] The positioning bolt 12 is threadedly connected to the screw hole 10, and the stud 13 passes through the positioning hole 11 and is threadedly connected to the bolt cap 14.

[0029] Specifically, the sliding seat 3 is slidably connected to the guide rail 4. When the rod body 2 expands and contracts, the first protective plate 7 and the second protective plate 8 drive the sliding seat 3 to slide. The protection of the rod body 2 is improved through the first protective plate 7 and the second protective plate 8. Through the connection between the positioning bolt 12 and the screw hole 10, and the stud 13 passing through the positioning hole 11 and connecting to the bolt cap 14, it is convenient to adjust the length of the protection and enhance the protection of the first protective plate 7 and the second protective plate 8.

[0030] Embodiment 2

[0031] Refer to Figure 4 , and on the basis of Embodiment 1, it is further obtained that a buffer mechanism 6 is installed at the inner side near the top of the second protective plate 8. The buffer mechanism 6 includes a connecting column 15, a shaft seat 16 and a connecting hole 17. The shaft seat 16 is used for installing at the top of the rod body 2. A screw groove 18 is opened outside the shaft seat 16. The connecting hole 17 is opened at the inner and outer sides near the top of the second protective plate 8. The connecting column 15 is movably installed inside the connecting hole 17. A knob 19 is fixedly installed at the outer end of the connecting column 15. A positioning disk 20 is fixedly installed at the inner end of the connecting column 15. A spring 21 is sleeved outside the connecting column 15. A screw rod 22 is fixedly installed on the inner side of the positioning disk 20.

[0032] The inner diameter of the connecting hole 17 is larger than the outer diameter of the connecting column 15, and the connecting column 15 is arranged to slide inside the connecting hole 17.

[0033] The spring 21 is located between the positioning disk 20 and the second protective plate 8, and the screw rod 22 is threadedly connected to the screw groove 18.

[0034] Specifically, the connecting column 15 passes through the connecting hole 17 and is fixed through the connection between the screw rod 22 and the screw groove 18, so that the top of the second protective plate 8 is fixedly connected to the rod body 2. Under the action of the spring 21 and the hinge 9, the second protective plate 8 and the first protective plate 7 can play a buffering role on the rod body 2, and further improve the protection of the rod body 2.

[0035] During the actual operation process, through the connection between the screw rod 22 and the screw groove 18, the second protective plate 8 is fixedly connected to the rod body 2. The rod body 2 expands and contracts through the cylinder body 1 and drives the second protective plate 8 to slide accordingly, so that the sliding seat 3 slides synchronously through the guide rail 4. The second protective plate 8 and the first protective plate 7 provide protection for the rod body 2;

[0036] When adjusting the length of the protection and disassembling, rotate the positioning bolt 12 and the bolt cap 14 to disengage the bolt cap 14 from the stud 13 and the positioning bolt 12 from the screw hole 10, take out the second protection plate 8, slide the second protection plate 8 up and down to make the lengths of the first protection plate 7 and the second protection plate 8 match the maximum length of the rod body 2 extending out, then connect the positioning bolt 12 in the screw hole 10, make the stud 13 penetrate through the positioning hole 11 and connect with the bolt cap 14 for fixation. The first protection plate 7 rotates through the connection of the hinge 9, which is convenient for the deployment of the first protection plate 7 and the second protection plate 8 and facilitates the cleaning and maintenance of the rod body 2;

[0037] When external sundries or stones collide with the first protection plate 7 and the second protection plate 8, the second protection plate 8 shrinks under the action of the spring 21 and the hinge 9. The spring 21 provides a buffering effect by supporting the second protection plate 8. By rotating the knob 19, the connecting column 15 drives the screw rod 22 to rotate and connect or disengage from the screw groove 18, for the disassembly and assembly between the second protection plate 8 and the rod body 2.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principle and spirit of the present invention.
